Network Information Services (NIS and NIS+) Guide
Troubleshooting User Problems
This section describes NIS+ problems that a typical user might encounter. Symptoms include:
- User cannot log in.
- User cannot rlogin to other domain
User Cannot Log In
There are many possible reasons for a user being unable to log in:
- User forgot password. To set up a new password for a user who has forgotten the previous one, run nispasswd for that user on another machine (you have to be the NIS+ administrator to do this).
- Mistyping password. Make sure the user knows the correct password and understands that passwords are case-sensitive and that the letter o is not interchangeable with the numeral 0, nor is the letter l the same as the numeral 1.
- "Login incorrect"-type message.
For causes other than simply mistyping the password, see "Login Incorrect" Message.
- The user's password privileges have expired.
- An inactivity maximum has been set for this user, and the user has exceeded it.
Edit the /etc/security/login.cfg, /etc/security/user, and /usr/lib/security/methods.cfg configuration files. (Add them, if they do not exist.) The following lines must exist (and not be commented) in these files:
NISPLUS
program=/usr/lib/security/NISPLUS
User Cannot Log In Using New Password
Users who recently changed their password now find they cannot log in at all, or are able to log in on some machines but not on others. Check the following possiilities:
- It may take some time for the new password to propagate through the network. Have users try to log in with the old password.
- The password was changed on a machine that was not running NIS+.
User Cannot Remote Log In to Remote Domain
User tries to rlogin to a machine in some other domain and is refused with a "Permission denied" type of error message.
To rlogin to a machine in another domain, a user must have local credentials in that domain.
Run nismatch username.domainname.cred.org_dir in the other domain to see if the user has a LOCAL credential in that domain. If not, do the following:
User Cannot Change Password
The most common cause of a user being unable to change passwords is that the user is mistyping (or has forgotten) the old password.
Other possible causes are:
